Chapter 3: BIOS Setup
The BIOS is a boot program located in a Flash Memory chip on the mainboard. It is used to
communicate with the hardware before the operating system (OS) takes the control of the
system. Its main function is to manage the setup of the motherboard and interface card
parameters, including simple parameters such as time, date, hard disk drive, as well as more
complex parameters such as hardware synchronization, device operating mode, and the
operating speed of the CPU.
Do not change the parameters inside the BIOS unless you fully understand their
meanings and consequences:
The parameters inside the BIOS are used to setup the
hardware synchronization or the device-operating mode. If the parameters are not correct, they
will produce errors, the computer will crash, and sometimes you will not even be able to boot the
computer after it has crashed. We recommend that you do not change the parameters inside
the BIOS unless you are very familiar with them. If you are not able to boot your computer
anymore, please refer to Chapter 2 Hardware Installation, section 2-5 Jumpers -
